Ive been contemplating removing the DTSS on my car while I have the rear differential out, and was just wondering how it feels removed vs stock? Truthfully I think it gives a slightly uneasy feel to the car when pushed to the limits, but I am used to it and know what it feels like and how to control it. What does it feel like when removed? Is the handling and grip at the limits worse with it removed? For those who removed it, were you pleased and would you do it again? Thanks

Limit of adhesion is higher and more predictable. Do it.

There was a good discussion here about a week ago. Dave at Mazdatrix went into detail on his opinions. Real good info. I hate to say this but do a search and try to find it.

wow, does the Dtss really suck that bad?> I mean jeez, Mazda obviously went thru great trouble to enable 'rear steer' on our awesome Rx-7. And i guess people just dont like it

I would like to drive a mazda with the Dtss Disabled, and see the handling characteristics. than compare with mine..

Yo,


Way mo' bettah. Dorifto time is extended, much more catchable and predictable.

Do a search on my name and DTSS...I did a write up/pictures.

I'd definitely recommend it.

Yeah the problem is that when you lose rear grip, the toe changes back to normal real fast, and screws your chances of catching it. Really annoying as I found at autocross.

It's kinda weird feeling the car rotate like it does with it on. The first time I drove it hard and I felt it do it's thing, I thought I was about to lose the *** and go flying into the trees! It's not a very secure feeling to me, so, if I had the money, I would remove it.

To me it feels like the rear end is connected to the car with a giant rubber-band when the DTSS does its thing. Like the back end slowly steps out, but Im not really sliding. Just really weird feeling. Like I said though, Im used to it and all, but still think Id like it gone. Ill try some more searches, I did some before I posted and basically only got about 1/2 voting they liked it and the other half saying no.

DTSS is good for novice drivers...it keeps the back end in check and when it does step out it's less violent. For experienced drivers though it numbs response time and predictability of a light rear drive car. If you autocross removing the DTSS and adding an LSD (if you don't have it) will make all the difference. Autocross is the place for a novice to learn how to drive their specific car...the road course is where you race hehe

Yes I have an LSD, and I dont like the "mushiness" feeling of the DTSS when it comes into play.

I've had the rear steer eliminators in for about a month. I love it. It actually feels like a rwd sports car now.

Here is the thread that you are probably looking for:
https://www.rx7club.com/forum/showth...hreadid=189077

Mazda's DTSS is similar to Nissan's HICAS (found in the 1989-1994 240sx, as well as the 300ZX). Nissan's HICAS would basically allow the rear wheels to steer as well. While this function is of benefit in parking as well as the slalom (at least w/ the Nissans), SOME drivers don't like it. Steve Millen (of Stillen), doesn't like the vague feel that this sort of "function" provides. It makes the rear feel unpredictable....something a race car driver does not like. (He offers a HICAS eliminator). HOWEVER, there are some people that do like the benefits that this "function" provides.

Whether you choose to use this function is up to you. Either way, given the age of the car, odds are...the bushings are toast. Time to decide whether to keep the function or eliminate it.

cheaper to ditch it I would imagine...mazda charges crazy $$ for all factory parts.

Ok this is new to me... Anyone care to inlighten me on this. Does all RX7s come with this? I have a 87 TII does my car have this? I have heard of the rear wheel steering on the nissan z but first time hearing it on the rx7.

Yes, it has it. All FCs have it. Rear Steer" was added to the RX-7 beginning with the 86 model. The rear geometry reacts to cornering "G" forces by changing the toe alignment on each wheel depending on the speed, loads, and body roll. The sensation the driver feels is the front wanting to steer into the corner, but is actually the rear steering to the outside of the corner. This all happens right when a sensitive driver is expecting the rear end to begin a slight slide which the driver would compensate for by some degree of opposite-lock steering input.

Here is a very good write up about the DTSS and the installation of the eliminator bushings..

Very interesting... Thank you!
I have raced for 3 seasons now in rx7s and done well.
I will just leave mine alone for now, I have bigger fish to fry!
